I am a contract programmer working on an off-shore natural gas platform project. I have 5 computers running at home in my office and was thinking about making all of them guests on a single hypervisor as a winter project. I brought along a small ITX sized PC for to help me get acquaited with hypervisors. It's CPU is missing Intel VT-d instructions, so I went to the local Best Buy store and bought a SSD upgrade kit for this company laptop. The laptop has VT-d features and is an i7. It is running on a spare partition but I will need to go back to the original hard drive soon because the Windows OS is complaining about needing re-activation. I just work on my hypervisor upgrade in my hotel room in the evenings and on the days that the helicopter doesn't fly because of weather. There isn't any way to grant remote SSH access until I get back home in January. Tom -- Public Keys: PGP KeyID = 0x5F22FDC1 GnuPG KeyID = 0x620836CF
